Eyewitness News teamed up with ABC News to conduct a year-long investigation into a supposed "miracle cure" that's peddled by the so-called "Church of Bleach," which has a chapter in Southern California.

The "miracle cure" is really a form of industrial bleach, but that doesn't stop believers from pushing the potion on the sick, the desperate, and perhaps most alarmingly, the parents of children with autism.

Kerri Rivera has made her name on the extreme fringes of the autism community. According to Rivera, when the full moon rises every 29 days, that's when parasites wreak havoc inside the guts of children with autism.

"Autism is curable," Rivera is heard saying in a video. "I like to convince people they can cure their kids."

Rivera tells desperate parents that parasites and other pathogens are to blame.
